Why stop at scanning photos in your phone?

With lower power sensors, head-mounted devices with always-on-sensors, and whatnot, why not sample real-time hashes that can tip LEO about potential crimes happening?

Then why sacrifice recall in order to achieve high accuracy?

Err on the side of uploading more hashes. Then feed it all into a ML so it can use other data to filter out potential false positives.

Then if in a distance future, any LEO wants to investigate you for whatever reason, the set of potential hashes associated with your account will provide sufficient evidence for any court to authorize further non-hashed data access (it doesn't matter if they were all false positives)
